Dry Carpet Cleaning

Dry Carpet Cleaning is a term that does not identify one cleaning process, but a variety of different cleaning methods. There are many different forms of dry carpet cleaning each with their own benefits and negatives. None of the methods provide the deep cleaning capabilities that truck mounted hot water extraction provides, but they have their place in the carpet cleaning industry. If, for example, you needed a method that dries in a very short time because you can not handle business down time, such as a hotel or air port, dry carpet cleaning might be a method that you should consider. Here are the most popular forms of dry carpet cleaning.

Bonnet Carpet CleaningBonnet Cleaning

Perhaps the most popular form of dry carpet cleaning, this method uses an orbital floor machine and absorbent cleaning pads to remove soil. The operator will first apply a cleaning solution to the carpet and the cleaning pads. They will then place the cleaning bonnet on the floor and place the orbital floor machine or buffer on the cleaning pad. The operator will then spin the pad over the carpet, removing soil as they go. The carpet is then groomed to remove spin marks and allowed to dry.
1. Quick dry times. Carpets cleaned with the bonnet cleaning method will generally be dry in under an hour.
2. Inexpensive equipment. Bonnet cleaning systems can be purchased for less than a thousand dollars. All that is needed is a low speed floor buffer, a few cleaning pads and a pump up sprayer.
3. Easy to operate.  This is an easy to learn cleaning method requiring very little employee training. Once the operator has learned to operate the buffer, they can begin working.
1. Limited soil removal. Because of the lack of flushing action, limited soil is actually removed.
2. Can damage some carpets. This process can leave swirl marks on some carpets, especially if the operator does not use enough liquid for lubrication.
3. Infective on many types of stains. Some stains, like pet stains, require more flushing action.

Dry Powder CleaningDry Powder Cleaning

Another popular dry carpet cleaning method that involves the use of a semi moist powder and a machine to agitate the powder. The machine, in most cases will use counter rotating nylon brushes to agitate the powder. To perform this method, the operator will sprinkle the semi moist powder onto the carpet. They will then turn on the machine and agitate the solution in two different opposing directions. After allowing the powder to completely dry, the operator will vacuum it up and out of the carpet.
1. Very quick drying time. Drying time with this method is generally counted in minutes.
2. Good agitation. The cleaning machines counter rotating nylon brushes are able to get deep into and between the carpet fibers.
3. Inexpensive equipment. Compared to truck mounted hot water extraction, this method uses very affordable equipment. Equipment can be purchased for around $2000.
1. Limited soil removal. Because of the very limited amount of moisture, soil removal is limited.
2. Some powder remains in the carpet. The powder used is very hard to remove from the carpet and trace amounts will be left behind. This may bother some people.
3. Solvent odors. Many of these powder cleaners use heavy solvents which can negatively effect sensitive consumers.

Foam Carpet CleaningFoam Cleaning

In this method of dry carpet cleaning, the operator will apply a shampoo solution to the carpet that has been worked into a foam. This solution is agitated and then extracted. Some variations of this method will use an encapsulating cleaning solution that is designed to absorb soil and then crystallize as it dries for later removal by vacuuming.
1. Quick drying times. Carpets are generally dry in less than an hour.
2. Portable machines. Machines are small and easily portable to allow for easy transport.
1. Limited soil removal. Because of the limited amount of moisture used, this method removes minimal soil.
2. Residue left behind. There is no true extraction step so a residue build up can be left on the carpet.
